Application filed May 6,

To all whom it may concern:

Be it known that I, JosEPH J. SMITH, a citizen ofthe United States, residing at Cambrid e, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Devices for Up erating upon the Cards of Carding Engines; and I do hereby declare the'following'to be a full, clear, and exact description of the invention, suchas willenable others skilled in the art to which it appertains to make and use the same.

The present invention relates to devicesfor operating upon a card of a carding engine and more articularly to means for supporting the stripping roll of a card stripping device in operative position.

In prior commercial card stripping devices, the stripping roll' is supported in operative position by means of brackets that project from the frame of the cardingengine which are provided with sockets in which the ends of the shaft that carries the stripping roll are seated. The stripping roll in such devices is driven from the cardingengine through a belt which passes over a pulley secured on one end ofthe shaftv of the roll so that there is considerable tendency for the roll to be laterally displaced'out of proper o operative position relatively to the card cyl-.

" tions, arrangements,

inder. Consequently, during the stripping operation, it two operators, one at each end of the roll, to hold the ends of the shaft properly seated in the socket bearingsl Moreover, as such "socket bearings in open upwardly, it is necessary to give the roll a downward movement'to position it on the brackets and an upward movement to remove it from the bracketswwhich frequently results in the stripping roll being injured byaccidentally striking one of the flats or other parts of the carding engine.

One of the objects of the present invention is to provide a novel and improved means for supporting the rolls of such devices which retains all of the advantages'of the prior constructions, while doing away with the disadvantagesu I v With this object in view the features of the present invention comprise certain construcand combinations of parts hereinafter described and claimed the advantages of which will be 'obviousto those Skilled in the art. a

has been necessary toemploy the brackets necessarily upwardly offset tions 34 are each provided with a pair of 1919. Serial No. 295,185.

The several features of the present invention will be readily understood from the fol lowing description and accompanying drawings in which: Figure 1 is a sideelevation of i a portion of a carding engine and 'a card stripping device applied thereto embodying the several features of the present invention in their preferred "form; Fig. Qisadetail view in side elevation of a bracket and co i block withf these parts a-detail view in front elev a bracket and bearing block in 1 The carding engine illustrated in'part in i the accompanying drawings comprises side frames 2. a card cyllnder l mounted between 1.

the side frames the periphery of which is indicated by a dotted line in-Fi'g. 1, and a-card' flat 6. In the illustrated'embodiment of the I present invention brackets 8 areadjustably secured to the outer-sides of the side frames of the carding engine by means of" bolts 10 brackets and are screwed into the side frames. The forward ends of the bracketsB'are proare "located substantially radial to the axis which extend through elongatedslotsin the of the card cylinder. The upperside 'of each 7 of the, tongues 12 is provided with a flat portion tion 15 parallel therewith and iwithan upwardly beveled portion '18. Y

The card stripping device ill ustrated the 14 and the under side with a flat pordrawings comprises the usual strippingroll 20 mounted in a casing22 whichisconnected to a suitablevacuum apparatus "through a flexible pipe 24. The'stripping roll 20 is mounted on a shaft 26 which extends through and is -journaled in the ends of the casing. On the left end--of the shaft'26 is secured a pulley 28. In the illustrated embodim'entof the present inventionthe endszof the shaft 26 extend through bearing blocks 30 which are located adjacent the ends ofthe casing. Each of the bearing blocks 30 is provided with a cylindrical portion 32 having a, which the shaft is journaled. Each of the bearing blocks portion 34:. The offset-p01 lining 35 in n I I 30 1s also providedwith an rectangular lugs 36 which are spaced to forms a rectangular channel or socket 38 .co'rre-.

sponding incrosssection to the tongues 12 of the brackets 8. The outer ends of the walls of the channels flare outwardly.

To bring the stripping device into operative position relatively to the card cylinder it is moved inta position to cause the tongues 12 on the brackets 8 to engage between the lugs 34 on the bearing blocks. In order to firmly lock the stripping device in position and to determine the position to which it is proper to move the stripping device relatively to the card cylinder, the upper lugs 34 of the bearing blocks are provided with downwardly spring pressed locking pins or plun gers 40, .the heads of which when the device is moved into operative position snap into transverse grooves or sockets 42 in the upper sides of the, tongues of the brackets 8. The heads of the plunge-rs 4Q are rounded to closely fit the sockets 42 and are mounted to slideiinapertures 44 .in the lugs 34. The plungers are pressed downwardly by means of springs 46 coiled about screws 48 secured to the heads of the plungers and interposed between the heads of the plungers and shoulders ,50 in the recesses 44. Thejdownward movement of the plungers are limited by the engagement'of the heads of the screws48 with the shoulders 50. The stripping device is held from longitudinal movement by the engagement of the inner walls 'ofthe channels 38 with the tongues 12.

It will be noted with this construction that the stripping device is firmly held whenin operative position, and that it may be moved readily into and out of operative positionby movement radially to the axis of the; card clyinder so that there is no danger 'of the stripping roll of the devicebeing'accidentally brought against the flats of the carding engine. The beveled surfaces 18 on the underside of the tongues 12 cooperate with the rear beveled end of the lower lugs of the bearingblocks 34 to relatively guide the bearing blocks and brackets into operative engagement. 7
